Questions
What counts as a scan?
One verification run over a block of text or a file. Faultline extracts every claim, checks each against live sources, and returns a trust score plus a list of anything it could not verify. Your plan’s monthly limit is the number of these runs.
Is there a free plan?
Yes. The Free plan gives you 5 scans per month with JSON and SARIF export and no card required. Personal ($19/mo) raises that to 100 scans, and Pro ($49/mo) to 500.
Do prices include tax?
No. Prices exclude sales tax and VAT. Stripe calculates any tax due at checkout from the location you enter, and it shows on the checkout page before you pay.
Can I cancel anytime?
Yes. Personal and Pro are month-to-month with no lock-in and no contract. Sign in, open Pricing, and select Manage or cancel subscription to use the Stripe-hosted billing portal. The plan stays active until the end of the billing period. For assistance, email faultline.web@nxtg.ai.
Whose AI provider keys do my scans run on?
Faultline’s. Hosted scans run on Faultline’s managed provider keys, so you never need your own for them. Free, Personal and Pro are capped by your monthly scan limit. Enterprise scan allowances are set in your contract.
Which AI providers does Faultline verify against?
Pro and Enterprise can route verification across every supported provider; Free and Personal use the default provider. Pro and Enterprise also unlock batch scanning, PDF audit export, team workspaces, and API access.
How is Faultline different from a grammar or plagiarism checker?
Those check style and originality. Faultline checks whether the factual claims in AI output are true — verifying citations against live sources and flagging fabricated references and hallucinations before they ship.
Do you store the text I scan?
Your text is sent to the Faultline engine and to the AI model providers that check it; the engine does not write it to storage. Signed-in history (the first 200 characters of each scan, with results) is saved to your account. Without an account, your history stays in your browser. A scan you share is stored for 30 days. Details are on the Privacy page.
